Expected Behavior

Insert rows successfully when insert without the default value field

Steps To Reproduce

from pymilvus import CollectionSchema, FieldSchema
from pymilvus import Collection
from pymilvus import connections
from pymilvus import DataType
from pymilvus import Partition
from pymilvus import utility
import json
import random

connections.connect()

dim = 3
schema = CollectionSchema(fields=[
    FieldSchema(name="id", dtype=DataType.INT64, is_primary=True, auto_id=False),
    FieldSchema(name="vector", dtype=DataType.FLOAT_VECTOR, dim=3),
    FieldSchema(name="flat", dtype=DataType.INT64, default_value=999),
])

collection = Collection("test_binbin_123", schema=schema)

collection.insert(data={"id": 4, "vector": [7,8,9]})
